Feat Boost: Chokehold (Improved Combat Maneuver [Grapple])

Character Operations Manual pg. 88
Whenever you have an opponent pinned, that foe can’t speak or perform actions that involve speaking or uttering sound using their voice (such as roaring, singing, and so on). Normally this prevents the target from using language-dependent abilities unless they have limited telepathy or a similar ability.
